The Limerick Generating plant, located along the Schuylkill, has offered the following emergency plan in case of a disaster or serious incident at the generating station.

"A power plant reactor cannot produce a nuclear explosion. The uranium
fuel contains very little fissionable material. As for radiation, the
complex structure of a nuclear power plant is designed to prevent the
release of radiation. A serious incident, however, could allow some
radiation to escape, most likely as a cloud, or “plume,” of radioactive
steam that would be carried away from the plant by the wind. The
degree of risk to the public would depend on the size of the plume, the
direction and speed of the wind, and other factors," according to the emergency brochure.
